WAGON=JACK.

SPECIFICATION forming part of Letters Patent No. 387,735, dated August 14, 1888.

Application filed April 9, 1888. Serial No. 270,107. (No model.)

To aZZ wit/0112 it may concern.-

Be it known that I, ERWIN A. REDFORD, of Ban Pleine, in the county of Portage and State of IVisconsin, have invented new and useful Improvements in iVagou-Jaoks; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings,and to the letters or figures of reference marked thereon, which form a part of this specification.

In the drawings, Figure l is a perspective view of my improved wagon ".ick. Fig. 2 is a perspective view of the same device shown in Fig. 1 folded together in form for easy transportation. Fig. 3 is a slightly-modified form of a part of the device.

The base consists of a hat supporting-piece, A, and an npwardlyextending block, B, rigid to or integral with the supporting-piece A. The post consists, preferably, of two upright pieces, G G, pivoted to the base by a bolt, D, through the lower ends of the uprights and through the block B. These uprights have one corner of their lower extremities rounded off at E, whereby the post may be folded down upon the base in the manner shown in Fig. 2. For securing the post in an upright position a hook, I secured and pivoted to the base, is adapted to engage in an eyebolt, R, fixed in the upright G, whereby the post may be secured in an upright position. A levenarm, G, is pivoted in the upper extremity of the post, one end, H, of which is adapted to serve as a handle, and the other end, I, is provided with shoulders K and L for engaging with the axles of wagons of different heights. The

shoulder L is preferably constructed in the form of a shallow recess in the top surface of the lever-arm, and the shoulder K is formed at the outer end of the lever-arm and somewhat lower down than the shoulder L. A retaining-rod, M, is pivoted at one end to the handle of the lever-arm and at the other end is provided with a cross-bar, N, adapted to engage with atoothed rack or rocks, 0, fixed on the edge or edges of the uprights C O. The object of this retainingrod iii is to hold the lever-arm G by the engagement of the crossbar N with the racks O 0 against tipping down at its end I when a wagonaxle is being supported thereon.

It will be observed that the lever-arm G and the retaining-rod M are located between the two uprights G G, and that they are so pivoted that when the hook F is disengaged from the eye in the upright Gthe device may be folded compactly together in the form shown in Fig. 2. If the wagon-jack is desired for use mostly at one locality, I insert a second bolt, D, through the lower ends of the posts and through the block B, wherebyin connection with the bolt D the uprights are secured rigidly to the base without using the hook F.

That I claim as new, and desire to secure by Letters Patent, is-

A folding wagon jack consisting of a base piece having a block, B, two uprights, G G, pivoted to the block B and provided with racks O O, a hook, F, adapted to hold the uprights in perpendicularposition, a lever-arm, G, pivoted in the top of the uprights G C,said lever-arm being provided with a shoulder, K, and a recess, L, the recess Lbeing higher than the shoulder K, and a retaining-rod, M, pivoted to the lever-arm G and provided with crossbar N, adapted to engage the racks O O, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
